To all whom it may aoaocm:

Be it known that I, HARRY D. Ynnxa, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certainnew and useful Improvements in Attachments for Coin- Controlled Mechanism for Vending Machines; and I do hereby declare the follow ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in attachments for coin-controlled mechanism used for vending articles and the object in view is to produce a simple and eflicient device designed as a safeguard to prevent more than one coin being inserted in the machine at the same time, thus rendering it necessary to depress a lever and operate the machine before the second coin may be inserted and utilized in the operation of the apparatus.

My invention comprises various other details of construction, combinations and ar rangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which:

Figure l is a rear view of a portion of the coin-controlled mechanism showing the ap plication of my invention thereto. Fig. 2 is a similar view showing the lever depressed and the parts raised to elevated position. Fig. 8 is an enlarged detail view in side elevation showing the means for holding the coin and tripping the same. Fig. 4 is a similar view in elevation showing the coin held from entering the slot. Fig. 5 is a view showing the lever depressed and the coin still held from entering the machine before the lever is released. Fig. 6 is a detail view of one of the coin arresting devices. Fig. 7

is a perspective view of a bracket arm which supports the coin arresting member and pawl. Fig. 8 is a detail View of one of the coin arresting members, and Fig. 9 is a detail view of a pawl.

Reference now belng had to the details of the drawings by letter, A designates the front wall of the casing of the coin-controlled machine and B a bracket arm secured thereto and which has pivotally mounted upon the pins D thereof upon which a coin is adapted to be deposited, preparatory to the successful operation of the apparatus, and a coin chute E is formed integral with said plate and is dis posed at an inclination. Said chute has a upon one edge thereof, and F is a lever pivotally mounted upon the pin F upon the bracket arm H which is struck up from the front wall of the frame. A tilting member G is pivotally mounted upon a pin G carried by said flanged plate and has a laterally projecting portion G upon which the coin is adapted to rest when inserted in the machine, and a spring G is fastened at G to the frame and its other end to an integral hook G upon the member G and serves to normally return the same and the lever F to their normal positions. Said lever carries a pivotal pin I in oppositely disposed flanges and to which a link J is pi"- oted at its upper end and its lower end pivoted to the flange of the plate C by means of the pivotal pin N.

A bracket member L is fastened to the casing by means of rivets L, shown in Figs. 1 and 2 of the drawings, and has a wing L apertured as at L for the reception of a pivotal pin 0 upon which a coin arresting plate Q, is mounted, a detail of which plate is shown in Fig. 8 of the drawings, and which is provided with a lug Q struck up from one edge and has a lateral projection Q upon its opposite edge and at its extreme widened end has an elongated slot (I A pawl, designated by letter R, a detail of which is shown in Fig. 9 of the drawings, has an aperture It therein through which a pivotal pin R passes, which is carried by the bracket member L, and said pawl is notched as at E which notch is adapted to engage the lug Q, when the pawl is in its normal position. A second coin arresting member, designated by letter S, a detail of which is shown in Fig. 6 of the drawing, is pivotally mounted upon the pivot O and provided with a finger S, which is slightly curved and has its forward edge inclined slightly and is in the path of the flange E, shown clearly in Figs. 1 and 2 of the drawings. curved slot S thereon and through which and the slot Q the pin R passes and which the flanged plate C Said member S has an elongated pin, passing through the two curved slots,

drawings in solid and dotted lines and designated by letter T.

lhe operation of my invention will be readily understood and is as follows When the parts are in their normal positions, as shown in Fig. 1 of the drawings, a coin may be inserted in the chute and, coming in contact with the pawl R, will cause the same to tilt from the position shown in solid lines in Fig. 8 to the position shown in dotted lines in the same figure, thus allowing the coin to be deposited in proper position upon the lateral projection G of the member G in readiness to be utilized in the successful operation of the machine. hen the coin comes in contact with the pawl, it tilts the latter, throwing the notch thereof out of engagement with the lug Q and allowing the member Q to fall by gravity to its lowest limit and which position is illustrated in Fig. l of the drawings, thus forming an obstruction, preventing another coin being introduced until the lever F first shall have been depressed to again raise the member Q to its normal position out of the path of the coin. In Fig. 5 of the drawings, the lever is shown in its depressed position at its lowest limit, the depressing or swinging down movement of the outer free end of the lever causing the chute E to tilt forward, allowing the free end of the member S to tilt down to the position shown in Fig. 5 and which also will form an obstruction to the coin entering the chute until the lever has been returned to its normal position through the medium of the spring G and which is accomplished by the flange E coming in contact with the curved edge of the finger S. After the lever returns to its normal position, the pawl automatically returns to its normal position, the notch R thereof engaging the lug Q, and holding the parts in readiness to be again operated by the insertion of a second coin.'

By the provision of the device shown and described, it will be noted that means is provided as a safeguard so that only one penny may be inserted in the machine at the same time, making it necessary to press the lever and operate the machine before a second coin may be inserted for another operation of the machine. I
